High-precision Positioner / Scanner for Microscope Objectives

P-725

PIFOC Objective Scanner with Long Travel Range

 Travel ranges to 460 µm

 Significantly faster response and higher

lifetime than motorized drives

 Fine positioning of objectives with sub-

nm

resolution

 Direct metrology with capacitive sensors:

Highest linearity

 Zero-play, high-precision flexure guide

system for better focus stability

 Compatible with MetaMorph imaging

software

 Out

standing lifetime due to PICMA® piezo

actuators

 QuickLock thread adapter for easy

attachment

 Clear aperture up to Ø 29 mm

Fast step-and-settle: Due to its stiff design, the P-725.2CL PIFOC can perform a 250 µm step to 1 % accuracy in only 25 ms (no load; 50 ms with a load of

150 g; with E-665.CR controller).
